To all whom it may concern:

Be it known that I, GOTTFRIED WVELGER, manufacturer, subject of theKingdom of Prussia, Empire of Germany, residing at Seehausen, districtof Wanzleben, Kingdom of Prussia, Empire of Germany, have inventedcertain new and useful Improvements in Baling-Presses, of which thefollowing is a specification.

My invention relates to improvements in baling presses for compressingloose and bulky material, such as chad, straw, hay, flax straw, and thelike, which compressing is desirable, for example, for transporta tion.

The object of the improvements is to provide a press of this class inwhich the material is more uniformly distributed over itscross-sectional area than could be done in presses heretoforeconstructed, and with this object in view my invention consists inproviding means for uniformly distributing the material to be baled overthe cross sectional area of the pressprior to compressin the same.

While my invention is particularly useful in combination with balingpresses wherein the presser chambers are disposed horizontally orsubstantially horizontally, I wish it to be understood, that myinvention is not limited to such use.

In order that my invention be more clearly understood, severalstructural embodiments thereof have been shown in the accompanyingdrawings in which the same letters of reference have been used in allthe views to indicate corresponding parts.

In said drawings Figure 1 is a diagrammatical view of a baling pressillustrating the invention, Fig. 2, is a side view of a baling pressequipped with my improved apparatus for distributing the material to bebaled prior to compressing the same,

Fig. 3, is a similar side view showing a modification of the apparatusfor distrib uting thematerial, Fig. 4, is a similar side view of thepress illustrated in Fig. 3 and showing the distributing member in a differ-ent position, Figs. 5 6, are side views of a further modification ofmy improved apparatus, the operative parts being shown in both figuresin different positions, and Fig. 7, is a detail view showing amodification of the apparatus in which the distributing member isadjustable.

In baling presses wherein the presser chambers are disposed horizontallyor substantially horizontally it has heretofore been found diificult ifnot impossible to compress the materials into bales of suflicientlyuniform density, because the material which is supplied into thepressing chamber from above is piled up on the bottom to form a flatpile. Particularly where short fiber material is to be baled, the pileis forced forward by the pressing plunger and forced against thecompressed material at the bottom thereof. Therefore the bales areconsiderably more dense near their bottoms than at their tops, and theycannot well be bound and are liable to fall apart again after leavingthe press.

The object of the improvements is to provide means in combination withbaling presses whereby bales of sufficiently uniform density areproduced. With this object in view my invention consists in providingmeans in the baling press whereby the material is prevented fromspreading on the bottom of the press and the portions of the materialwhich are near the bottom are in part raised up again to the top of thepress.

In order that the invention may be clearly understood, I have shown inFig. l a diagram illustrating the preferred method of lifting thematerial, which method is particularly designed for use in a balingpress of the aforementioned type. As is shown in the said figure, withina horizontal or substantially horizontal chamber or channel a plunger 11is mounted for reciprocation, by means of which the material iscompressed into a bale 12. The material is supplied through an opening13 provided in the top wall of the chamber 10, and when thus supplied itis liable to spread on the bottom of the chamber in the form of a fiatpile 17. To prevent this a holding member 14 is passed into the frame 10through the opening 13, which holding member consists,

for example of a rack, a foraminated plate, an imperforate plate, or thelike, and which can be rocked about a stationary or movable axis 15. Theoperating mechanism for the rack 14 is connected with the operatingmechanism of the plunger 11, and it is moved thereby in such a way, thatupon the return stroke of the plunger it assumes a more or less uprightposition with its end extending downward into the chamber 10 and permitsthe material to fall into the movable part of the press.

chamber. Upon the forward or compressing stroke of the plunger the rackis rocked upward. Thereby the portion 16 of the material which in thefigure is marked with hatchings is lifted upward and in front of theupper portion of the previously compressed material, that is into theposition marked with crossing hatchings, where the material iscompressed by the plunger 11 is equipped with my improved apparatus.

A press of the construction sliown, but without the rack, has heretoforebeen used for compressing hay, straw, and the like. As shown in the saidfigure, above the chamber 10 of the press a plate, sieve, or rackl-i isso mounted on a stationary rock shaft 15, that it is rocked by itsweight or by spring action into the upright position shown in full lineswhen the plunger 11 is moving backward and away from the bale 12. Whenin this position the rack 14 does not interfere with the filling of thechamber, so that the material can fill the space provided between therack 14: and the front face 18 of the compressed bale 12. Upon itscompressing stroke the plunger 11 engages the rack 14: with its upperedge 19 and rocks the same upward and into the position shown in dottedlines, and in this movement the lower edge 20 of the rack describes thecurved path w. The major portion of the material piled up on the bottomof the frame is thus lifted upward, and while the edge of the rackapproaches the upper part of the press the said material is spread overthe front side of the bale, sot-hat the plunger 11 which immediatelyfollows the edge 20 is enabled to compress the material which has thusbeen brought in front of the upper part of the bale. When the plunger ismoving backward the same operation is repeated.

Instead of operating the rack directly from the plunger I may alsooperate the same through the intermediary of a gearing connected withthe plunger or with another If desired the rack may be jointed to theplunger itself,

' and in this case it may be rocked either by stationary stops or bylinks which are jointed to a point of the rack located away from itspivot.

In cases where the press is designed for baling different materialswhich drop from the rack more or less slowly, I prefer to have the rackadjustable toward and away from the bottom of the chamber and the frontface of the bale. This may be done in different ways. To show what maybe done I have illustrated in Fig. 7 a construction in which the rack isadapted to be adjusted together with its pivot which for this purpose ismounted on a slide block 21 adapted to be vertically adjusted within aslotted bracket 22 mounted on the frame of the press. Or theconstruction may be such, that the rack is longitudinally shiftedrelatively to its pivot. The invention may also be embodied in pressesof a difierent construction, or in presses which are used for balingother fibrous materials. I

Instead of mounting the rack for rocking movement on a rock shaft, I mayguide the same along a rectilinear path, or I may combine rockingmovement with movement along a rectilinear path.

My improved apparatus is the more effective, the more nearly the path ofthe outer edge of the rack approaches the vertical line.

In Figs. 3 to 6 I have shown several modifications in which the path ofthe edge follows more closely the vertical line, than in the form shownin Fig. 2, and in which, notwithstanding this, the said rack is pivotedabove the path of the plunger and its lower edge is disposed near thebottom of the chamber when in its retracted position. For this purposethe axis of the rack is made shiftable, and it is so connected with theplunger or its driving gear, that it is shifted backward and in adirection opposite to the stroke of the plunger when the latter performsits compression stroke. Thereby the path of the edge of the rack is mademore steep when it is being rocked about its pivot, and the said pathsubstantially follows the front face of the compressed bale.

In the form shown in Figs. 3 and 4 the pivot 25 of the rack 26 ismounted on a rocking lever 27 the fulcrum 28 of which is locatedintermediate the ends of the lever on a relatively fixed part, forexample on the frame 29. To the said lever a spring 30 is connectedwhich tends to pull the same into the position shown in Fig. 3. The freearm of the lever 27 extends into the path of a stop 31 which is movabletogether with the plunger 32 and is adapted to carry along the leverinto the position shown in Fig. 4f when'the plunger performs itscompression stroke. When now the rack 26 is rocked upward by theplunger, and its pivot is shifted to the left by being mounted on thelever 27, the lower edge 33 follows the path at which is very steep ascompared to the path m followed by the rack edge 20 of the example shownin Fig. 2. In order to make the movement of the rack more easy and toavoid wear of the parts the plunger 32 is preferably provided with oneor more rollers 34 for guiding the rack 26.

In the form shown in Figs. 5 and 6 the fulcrum 40 of the lever 41 whichcarries the pivot 42 of the rack 43 is located below the frame 44, andat one end of the lever, while it is connected by means of a link 45 ata point intermediate its ends with a rocking lever 46 mounted on apivot.47. The lever 46 is rocked by the plunger stops 48 cooperatingwith a spring 49, and the mechanism connecting the plunger and the leveris constructed substantially in the same way as the corresponding partsof the form shown in Figs. 3 and 4. The rack 43 bears against one ormore guide rollers 51 which are mounted in stationary bearings 52, andit engages the said rollers through the intermediary of a cam piece 53secured to the rack. It will readily be understood, that the said campiece serves to shift the rack with its edge 50 toward and away from thefront face of the bale, while the rack is being rocked; As compared tothe form shown in Figs. 3 and 4 the form shown in Figs. 5 and 6possesses the advantage, that by properly shaping the cam piece 53 avertical and rectilinear path can be imparted to the outer end of therack, wherebythe effect of the apparatus is considerably improved. Theshape of the cam 53 can easily be determined by experiment. The otherparts, for example the plunger 55 and its driving .gear may beconstructed in the usual manner.

If it is desired to have the outer end 50 of the rack 43 adjustabletoward and away from the front face, for the reason ex plained withreference, to Fig. 7, the bearing 54 for the pivot 42 and the cam piece53 may be adjusted longitudinally of the rack 43, as has been indicatedby additional screw holes 56 provided in the rack 43.
